self-fluxing alloy powder


Chengdu WOCO carbide Industry Co.,Ltd

     which was established in the hometown of hard metal of China--- ChengDu city in Sichuan province. A professional Chinese manufacturer of tungsten carbide products such as drawing die,indexable inserts shims, drilling bits, drawing dies, cold forging dies, carbide bars, carbide rods, carbide balls, carbide burrs, etc. Along with our company growth, we hope to build business with more companies abroad

Spray melting using self-fluxing alloy powder can be divided into the nickel base and cobalt base and iron base and containing tungsten carbide fluxed alloy such as four series.
 
 

Each classification list info below

 
The metal nickel borosilicate series, spray welding layer is not high hardness, good toughness. Resistance to thermal shock, at 600 ℃ still has good abrasion resistance and corrosion resistance. Boron and silicon in the alloy strengthening the effect of solid solution, such as nickel boride hard phase dispersion hardening effect. Nickel chrome borosilicate series from metal chromium dissolved in nickel, solid solution strengthening effect, formed a stable Ni - Cr solid solution, and improved the spray welding layer of oxidation resistance, heat resistance, corrosion resistance and wear resistance. This type of alloy besides containing nickel boride, also contain chromium high hardness boride (CrB) and chromium carbide (such as Cr23 C6, shape C3); High carbon content may also contain boron carbide. Cobalt-based fluxed alloy of chromium and cobalt form stable solid solution, chromium has a strong and improve oxidation resistance. Tungsten increases the heat intensity and high temperature hardness of the spray welding layer, and age hardening effect. Boron in addition to improve self fluxed alloy, and forming boride hard phase.
 
Iron base self-fluxing alloy powder for austenitic stainless steel type, to maintain good self fluxed, the alloy of nickel content must be kept in more than 28%, slightly lower than the nickel base alloy. This series of alloy spray welding layer has good wear resistance, has certain heat resistant, corrosion resistant performance. Containing tungsten carbide fluxed alloy powder by spray welding of nickel base and cobalt base or iron base self fluxed alloy powder with a certain proportion of cast tungsten carbide or sintered tungsten carbide particles. Containing tungsten carbide from the fusion of gold at the end of the spray welding layer has very good resistance to abrasive wear performance.
